Theater-goer expected more after accident

DEAR HARRIETTE: I recently went to see a musical that I had been looking forward to for months. The theater was packed, and the performance was absolutely amazing. About halfway through the show, though, I realized I needed to use the restroom. I tried to hold it until intermission, but eventually I just couldn’t wait any longer. Since the theater was dark, I carefully made my way out of my row, trying not to disturb anyone, but as I was walking down the aisle, I didn’t see a small step in the dim lighting.
